Not sure what kind of information you are looking for. Based on the comparison link you provide to ark.intel.com the significant difference between the two parts appears to be the system bus speed, which could affect some throughput measurements.
From a software perspective they are the same.
I think the "Maximum Turbo Frequency" number stated for the 430M must be a mistake. I would guess that it is really supposed to be 2.53 GHz.
